Filed: 2002-07-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a welding structure and a welding method of a bus bar for welding the bus bar and a mate member being welded with good appearance while stabilizing the bonding force.  <P>SOLUTION: Since protrusions 33 and 33 of a bus bar 30 on the opposite sides of a slit 32 are tapered, the protrusions 33 and 33 melt readily as compared with a conventional case and bonding force is stabilized at a welded part. The welded part becomes compact because the bus bar does not require a conventional raised wall. Furthermore, difference in the shape is reduced between the welded protrusions 33 and 33 because both protrusions 33 and 33 melt readily and appearance is enhanced at the welded part.  <P>COPYRIGHT: (C)2004,JPO
